In my case, after studying several offers I decided on one (apparently harmless), I tried a Telegram bot that promises to generate a fraction of bitcoin per second and all I had to do was keep it active once at least every 24 hours . Subsequently, in order to collect, he had to meet 2 basic requirements:

1. Invite 10 people
2. Have a minimum balance of 0.05BTC.

To my surprise when trying to make my first withdrawal, after fulfilling the aforementioned requirements, a notice appears that I must wait 30 business days for the withdrawal to take effect unless I change plans by depositing a certain amount of bitcoin.

In conclusion the money never reached me.
